ASSAIJ'S. GORAYEB, OF NEW YORK, N. Y.

PORTABLE ANTENNA.

Application filed September 15, 1923. Serial No. 662,971.

To all whom it may concern:

Be it known that AssAn S. GORAYEB, a citizen of the United States, residing at New York, in the county of New York and State of New York, has invented certain new and useful Improvements in PortableAnt-ennae, of which the following is aspecification.

This invention relates to radio apparatus and more particularly to a portable antenna.

One of the principal objects of the present invention is to provide a casing for the an- .tennawire which is portable whereby the same n'iay b'e placed anywhere it-is desired when set up'in position for use.

A further object of the invention is to provide a portable antenna. which is of such a construction as to enable the same to produce the desired results regardless of the position.

in which the same is supported, it being desirable, however, to place the casing supporting the antenna in awindow frame,

:thereby obviating the necessity of having to employ a special support; and 'fUTthBIHIOIE preventing the accidental displacement of the same. A still further object of'the invention is to provide a portableante'nna which includes means for connection to a window sash when the same-is supported on a window frame, whereby the capacity of the antenna may be adjusted to meet the demand. 7

Another important object; of the inventor isto provide a portable antenna wherein means is provided for holding the conline 2 2 of Fig. 1;

volutions of the antenna; wire in spaced relation whereby interference with one anotheris prevented.

A still further object of the invention is to provide a portable antenna which is simple in construction, strong and durable, and further well adapted for which it is designated.

Other objects and advantages of this invention" will, become apparent during the course of the following description.

In the accompanyingdrawings forming;

a part of the specification, and in which like numenals designate like parts throughout the same,

Figure 1 is a front elevation of a window showing my "invent on in position thereon;

Figure 2 is a. vertlcal section taken on Figure 3 is a lo' itudinal section of the casing showingthe arrangement of the an- 'tennawire onthe bottom wall thereof.

the purposes for V the'binding posts is a wire 6 which is adapt-- Figure 4 is a sectional view taken on line H of Fig. 3.

Figure 5 is a modification of the present invention showing a. cabinet wherein is supported the portable antenna in front elevation.

. Figure 6 is a vertical section thereof.

Figure 7 is a detailed perspective view of the antenna wire supporting frame, and

Figure 8 is a fragmentary section of'one corner of the frame showing a; portion of the wire in position thereon.

In the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the portable casing forming a part of the antenna andis substantially rec-' tangular, as clearly shown in the drawings. It is also tobe'understood that the .casing is constructed of any suitable material desired, and I do not wish to limit myself to any particular kind of material. The bottom in the respective ends thereof, and these slots are preferably arranged in parallel spaced relation, as'clearly shown in Fig. 3 of the drawings, for the purpose to be presently described.

Extending around both the upper andbottom faces of the bottom wall 2 of the portable casing lis the antenna wire designated by the numeral 4. The latter-is so arranged thereon as to have the convolutions thereof receivable in the slotted ends of the bottom wall whereby each turn of the wire is'spaced from its adj acent turn, whereby. interference between the several convolutions is prevented. The antenna wire 4 has itsend s' connected with the binding posts 5, as shown in Fig. 2 of the drawings, and leading from ed to connect with. the receiving set (not shown). v

In the present. construction I have shown the portable casing 1 supported upon the window-sill B of the window frame A so" that the casing fits snugly between the side rails of the window frame and adjacent the lower sash C. However, the casing 1 may be supported in any other desirable place as upon an automobile running board, or the like, and I do not wishto confine myself to the pa-rticular'support upon which my'port able antenna may be placed.

It Q I BfiIQQS desirable to adjust the capacity of the antenna wire and to this end I i ave provided within the portable casing 1 a longitudinally extending roller 7, which. is journaled in the end walls of the casing in any suitable manner, and upon which is supported the wire screen 8. The free end thereof is adapted to extend through a suitable elongated slot provided in the upper wall of the casing, as clearly shown in Fig. 2 of the drawings, and secured thereto is the strip 9, the latter being of a greater width than the opening so as to prevent the free end of the screen from entering the casing.

Mounted upon the upper portion of the strip 9 adjacent its respective ends, are the clamping elements 10. These clamping ele ments are adapted to cooperate with the pivoted catches 11 which are associated with the window sash raising lugs 12. The latter are mounted upon the window sash C adjacent the bottom thereof for raising and lowering the sash as may be desired. EX- tending from the binding post 5 is the spring finger 13 and the free end thereof is adapted to engage the rolling screen 8 at all times, whereby a continuous contact be tween the rolling screen and the binding post and the antenna wire is provided.

The operation of the rolling screen 7 whereby the capacity of the antenna is adjusted and regulated to the desired degree may be briefly stated as follows :The window sash C is raised through the medium of the lugs 12 and as the catches 11 carried thereby are in engagement with the clamps 10 mounted upon the strip 9, the screen 8 will be raised simultaneously, thus permitting the adjustment of the antenna to the proper capacity, it being understood, of course, that the spring finger 13 is at all times in engagement with the screen upon the roller 7.

When it is not desired "to use the screen 8, the pivoted catches 11 are detached from engagement with the clamps 10, and upon raising of the sash C, the operation of the screen and the adjustment of the capacity of the antenna will not be affected.

In Figs. 5 and 6 of the drawings a modification is shown w erein the numeral 14 designates a substantially rectangular cabinet having the hinged doors 15 provided on the front thereof, and adapted to be removably supported within the cabinet is the rectangular frame 16. This frame has its walls provided with slots arranged in spaced relation with one another and preferably formed at the corners thereof as clearly shown at 17 in the drawings, for the purpose of receiving-the convolutions of the antenna wire 18, whereby the latter is held in proper supported position thereon, so that the convolutions will not interfere or touch one another. The upper wall 19 of the rectangular frame 16 is provided with a series of spaced apertures 20.

The frame 16 is furthermore provided with a division plate 21 which forms compartments within the frame to receive the radio apparatus which is commonly associated with the antenna wire and as the same forms no important part of the present invention, it is not thought necessary to go further into detail relative the same, it being sufficient to state that the parts are so arranged within the cabinet 141 as to render the device portable and provided means for receiving all the essential parts necessary in order to obtain the desired results.

It will thus be seen from the foregoing description that a portable antenna has been provided which may be readily placed into an operative position upon a suitable support whereby the same will occupy a minimum amount of space and one which is of such a construction as to permit the same to be manufactured at a minimum cost and also in a simplified manner.

It will also be further noted that by providing a portable antenna with a rolling screen constructed of metal therein, which may be detachably connected to a window sash, the capacity of the antenna may be adjusted so as to produce the desired results without employing any complicated or expensive means.

From the foregoing description of the construction of my improved apparatus, it will be seen that I have provided a simple, inexpensive and elficlent means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion, and in the minor details of construction mav be resorted to, without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what I claim is 1. The combination with a window frame and a window sash therein, of a portable antenna, the latter comprising a casing adapted to be supported on said window frame, an antenna wire wrapped around the bottom wall of said casing, and means connected with said casing and said window sash for adjusting the capacity of said the capacity of the antenna may be adjusted upon the raising and lowering of said window sash.

3. The combination with a window frame and a window sash therein, of a portable antenna, the latter comprising a casing adapted to be supported on said window frame, the bottom wall of said casing having its ends slit longitudinally, an antenna wire havin the convolutions thereof receivable 1 in said slots, a rolling metallic member nection between said rolling member and 15 said antenna wire.

In testimony whereof I afiix my signature.

ASSAD S. GORAYEB.
